Answer:

Silicon forms four covalent bonds with hydrogen. The formula of the compound is SiH4. Germanium forms four covalent bonds with chlorine, the formula of the compound is GeCl4

Explanation:

The outermost shell of group 14 elements contains four electrons, which can combine with four other atoms having one unpaired electron in their outermost shell to form four electron pairs or a complete octet as required by the octet rule.

A sample of sulfur dioxide (SO2) is initially at a temperature of 105C, a volume of 15 L, and a pressure of 1.5 atm. If the volu

Agata [3.3K]

The new pressure is 1.08 atm

From the question, we are to determine the new pressure

Using the General gas equation,

$\frac{P_{1}V_{1} }{T_{1}} = \frac{P_{2}V_{2} }{T_{2}}$

Where P₁ is the initial pressure

V₁ is the initial volume

T₁ is the initial temperature

P₂ is the final pressure

V₂ is the final volume

and T₂ is the final temperature

From the given information,

P₁ = 1.5 atm

V₁ = 15 L

T₁ = 105 C = 105 + 273.15 = 378.15 K

V₂ = 25 L

T₂ = 181 C = 181 + 273.15 = 454.15 K

P₂ = ?

Putting the parameters into the equation, we get

$\frac{1.5 \times 15}{378.15} = \frac{P_{2} \times 25 }{454.15}$

$P_{2}= \frac{1.5 \times 15 \times 454.15}{25 \times 378.15}$

P₂ = 1.08 atm

Hence, the new pressure is 1.08 atm

Sodium bicarbonate is used to neutralize the remaining HCl at the end of the reaction. The initial products of this reaction are

V125BC [204]

Answer:

Kindly check explanation section.

Explanation:

Since, the question requires the chemical reaction to be written in lewis for the the processes involved in this particular Question/problem that is to say the neutralization process and the decomposition process. The lewis structure is given in the attached picture.

For the first process; Sodium bicarbonate reacts with HCl to produce the carbonic acid and a salt, known as Sodium chloride.

Na2CO3 + 2HCl ----------> 2NaCl + H2CO3.

The second process shows the decomposition of Carbonic acid into carbon dioxide and water.
